This change is meant to both improve the performance and reduce the size of
ixgbe_tx_map. To do this I have expanded the work done in the main loop by
pushing first into tx_buffer. This allows us to pull in the dma_mapping_error
check, the tx_buffer value assignment, and the initial DMA value assignment to
the Tx descriptor. The net result is that the function reduces in size by a
little over a 100 bytes and is about 1% or 2% faster.
